medium Tenable Self-Hosted Container Security Plugin ID 426216

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - A flaw was found in Open vSwitch where multiple versions are vulnerable to crafted Geneve packets, which
 may result in a denial of service and invalid memory accesses. Triggering this issue requires that
 hardware offloading via the netlink path is enabled. (CVE-2023-3966)

 - A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual
 machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted
 packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary
 IP addresses. (CVE-2023-5366)
